关于一些函数的解释

miaomiaoacmlan

EvaluateSurface（）函数是什么意思啊，我看过帮助文件里面说：Evaluates a surface at a U,V parameter.
Evaluates是评估，估计...的值，本人英语不好，翻译不出函数的意思，只知道最后输出的值是一个3D点的数组
还有为什么有些函数我在查（按F1）帮助文件时没有搜到啊，比如函数AddPointAtR1Parameter()，是因为我的犀牛版本老么，没有新的函数

EvaluateSurface
Evaluates a surface at a U,V parameter.

Syntax
Rhino.EvaluateSurface (strObject, arrParameter)

Parameters
strObject
Required.  String.  The object's identifier.

arrParameter
Required.  Array.  An array containing the U,V parameter to evaluate.


Returns
Array
A 3-D point if successful.

Null
If not successful, or on error.


Example
Dim strObject, arrDomainU, arrDomainV, arrParam(1), arrPoint

strObject = Rhino.GetObject("Select a surface")

If Rhino.IsSurface(strObject) Then

arrDomainU = Rhino.SurfaceDomain(strObject, 0)

arrDomainV = Rhino.SurfaceDomain(strObject, 1)

arrParam(0) = arrDomainU(1)/2

arrParam(1) = arrDomainV(1)/2

arrPoint = Rhino.EvaluateSurface(strObject, arrParam)

Rhino.AddPoint arrPoint

End If
